All of those below Temperature, Precipitation, Snow and Degree Day statistics.

Temperature Max/Min/mean Temperatures for each month as well as dates when lowest/highest values occurred.The last for columns list the number of days of exceedance of the most common thresholds: Max Temp >=90F, <=32F, Min Temp <=32F, <=0F

Precip/Snowfall Mean, Highs and Lows, Mean Extremes and Number of days exceeding 0.01In, 0.10In, 0.50In, 1.0In.

Temp/Precip/SnowTemperature Statistics as above as well as Mean and Highs for Precipitation and Snowfall.

Units
Data can be obtained in metric or English units.

Note: degree day calculations are preformed
with base temperatures in Fahrenheit.

English:
Temperatures in Fahrenheit
Precipitation/Snow/Pan Evaporation in Inches
Wind Movements in Miles

Metric:Note: native database units are English.
If you choose metric, be aware that data values loose precision
since they are converted from English units and will be rounded.
Temperatures in Celsius
Precipitation/Snow/Pan Evaporation in Millimiter
Degree Days: °C HDD = (5/9) x (°F HDD)
Wind Movements in Kilometers

Max Missing Days The number of maximum missing days allowed in a month.
Months with more than this number of days missing will be omitted from the analysis.
